2. 1. Content and In Vitro Accessibility of Provitamin. A Carotenoids in Some Tanzanian Vegetables and Fruits Effects of Traditional Processing and Preparation, and Influence on Vitamin A Status

   Author : Generose Ishengoma Mulokozi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in vitro accessibility; sunflower oil; solar cabinet drying; women; all-trans-beta-carotene; alpha-carotene; open sun-drying; vitamin A; provitamin A carotenoids; plasma; breast milk; fruits; vegetables; red palm oil; Tanzania; beta-cryptoxanthin; pregnancy; children;

   Abstract : Vitamin A deficiency is among the major nutritional problems in Tanzania as in many developing countries. It mainly affects children and pregnant and lactating women. The basic cause of this problem is related to the diet, which contains little preformed vitamin A and plant foods with a low content and bioavailability of provitamin A carotenoids. READ MORE

4. 2. Developing IPM tools for greenhouse cucumber production in Sweden – a participatory action research approach : control of the European tarnished plant bug and cucurbit powdery mildew

   Author : Mira Rur; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Two of the most important plant protection problems in Swedish cucumber production are the European Tarnished Plant Bug (ETPB), and Cucurbit Powdery mildew (CPM). The control of the ETPB relies on Imidacloprid, a pesticide, which breaks down slowly and is harmful to beneficial insects. READ MORE

5. 3. Dietary Fatty Acids, Body Composition and Ectopic Fat : Results from Overfeeding Studies in Humans

   Author : Fredrik Rosqvist; Ulf Risérus; Tommy Cederholm; Ian Macdonald; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Linoleic acid; Palmitic acid; SFA; PUFA; Fatty acids; Body composition; Liver fat; Ectopic fat; Adipose tissue; Medicinsk vetenskap; Medical Science;

   Abstract : The aim of this thesis was to investigate the effects of dietary fatty acids on body composition and ectopic fat in humans, with emphasis on the role of the omega-6 polyunsaturated fatty acid (PUFA) linoleic acid (18:2n-6) and the saturated fatty acid (SFA) palmitic acid (16:0). The overall hypothesis was that linoleic acid would be beneficial compared with palmitic acid during overfeeding, as previously indicated in animals. READ MORE

6. 4. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

   Author : Julia Wolska; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

   Abstract : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. READ MORE

7. 5. Phytoremediation of soil contaminated with per- and polyfluoroalkyl substances (PFAS)

   Author : Winnie Nassazzi; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Per- and polyfluoroalkyl substances (PFAS) are anthropogenic compounds recognised for their persistence, mobility and potential toxicity. This thesis examines the efficacy of phytoremediation as a potential technique for managing PFAS-contaminated soil and groundwater. READ MORE
